Exterior
The hull is very sturdy. It was 17.3 meters long and 3.75 meters wide. It’s painted, so it looks great. There are no particular issues.
Bridge/Marine Toilet/6 kW Generator
The rotating porthole operates properly. There is a private toilet next to the bridge. Although it is deep, its width prevents it from feeling cramped. There are sliding doors on both sides. It appears there used to be a semi-flybridge. A 6 kW industrial diesel generator is neatly built into the space beneath the aft hatch.
Cockpit/Cabin
There is no switch for the thruster, so some maintenance is required.
Cabin

Fore Deck
The deck was very sturdy. It has been raised one step to create a flat deck. The coaming is wide, making it easy to get on and off. A seawater deck hose is installed on the bulwark. A hydraulic bow thruster is built into the space under the hatch, but it is currently inoperable. Apparently, a switch or some maintenance is required to make it work.
Aft deck
A sturdy deck. There is no fish hold here, but there is an ice locker.
